            Bug ID: 91262
           Summary: PDF gradient incorrectly rendered
           Product: poppler
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
          Assignee: poppler-bugs at lists.freedesktop.org

Test case

The PDF gradient generated by following LaTeX document is rendered incorrectly:

\documentclass{standalone}

\usepackage{tikz}
\usetikzlibrary{shadings}

\begin{document}
\begin{tikzpicture}
\shade[shading=color wheel, opacity=.6, shading angle=220] (0,0) circle (1);

\end{tikzpicture}
\end{document}

Okular renders this incorrectly: grid lines and very bad gradient resolution
(see screenshots). The grid lines disappear when "shading angle=220" is removed
from the source.
